eventfd: evntfd assumes to take two arguments instead it
should be one evntfd expects two therefore implement both syscalls with
correct parameters

Linux has provided these functions since the 2.1.x era, so no need to
keep these around. We'd rather find out when things are missing (and
fix that) than fall back to the unsafe hacks.

Some arches got this fix, but many did not. So copy the ifdef logic to
the ones that missed it to fix behavior in linux-2.6+.

Fix the implementation of mmap based on the mmap2 system call, to
construct pgoffset from offset with an unsigned shift rather than a
signed (off_t) shift. The mmap2 test in the testsuite catches this case
by mmap'ing with a large offset (with the sign bit set). The signed
shift repeats the sign bit making the page shift way out of range. This
is already fixed similarly in mmap64().

Since glibc has split out arch-specific stuff to bits/epoll.h, we can
pull that sanity back into our tree and drop the arch ifdefs.

Older kernels use __NR__llseek for a 64-bit lseek syscall. Newer
kernels use __NR_llseek. This patch fixes the implementation of
lseek64 to use the __NR_llseek syscall if it exists.

The test for generating a stub for getpgrp was wrong and would
result in duplicate symbols when building without __NR_getpgrp,
but with __NR_getpgid and __NR_getpid.
A closer look at the getpgrp implementation using getpgid showed
that getpid was being called to pass the current pid to getpgid.
This is unnecessary because passing 0 to getpgid returns the
pgid of the current process.
This patch cleans up the getpgrp implementation and the stub test.

Some arches check the size in INLINE_SYSCALL() and barf if it's
too big (i.e. a 64bit value getting truncated to 32bit).

Some targets include this implicitly, but pull it in explicitly for those
which don't to fix building for them.

The current code will sometimes cast the offset to an unsigned long.
On 32bit systems, that doesn't make much sense since we always know
that the off64_t type is 64bits. So drop the ifdef logic, cast it
to an unsigned 64bit value, and then do the shift.
If the system is 32bits, and the address is still too large, then
there's really nothing we could do about it anyways, so the extra
ifdef logic wasn't helping.

glibc has split off the arch-specific flag definitions (like
SFD_NONBLOCK) into <arch>/bits/signalfd.h, so that there are no longer
multiple redundant copies of the entire header file. We will adopt the
same scheme in uClibc.
Special cases are included for: alpha mips sparc
hppa was omitted because it has not been updated in glibc.
All others use the common definition.

[BZ #7040]
* sysdeps/unix/sysv/linux/sys/inotify.h: Second parameter of
inotify_rm_watch should have type int.
This change allows us to copy inotify.h verbatim from glibc into uClibc.

This is needed for stat'ing loop devices > 255
since otherwise kernel returns EOVERFLOW becasue
it needs st_rdev/st_dev to be larger than 16bits but
in kernel it uses __old_kernel_stat for stat

On several architectures __NR_ulimit syscall number is currently
defined but it is remapped onto sys_ni_syscall, while on other
architectures they are not longer defined.
So use {get,set}rlimit only to implement ulimit interface.
It fixes LTP ulimit01 test case.
